In the summer, after a great festival at the Hakurei Shrine, Yukari Yakumo persuades Reimu to form a team and challenge other girls in a mahjong tournament. Touhou Juunana Po, literally translated as Eastern Seventeen Steps, also known as Touhou Landmine Mahjong, is a turn based mahjong battle game developed by illuCalab. The game features ten pairs of characters and applies slightly different rules where victory is determined by discarded tiles by both players or when one of player has dealt 17 tiles. When playing with the character pairs, each character has different spells that can be selected before the match where each spell can affect status and tiles.
